You can use one or multiple NFS servers to store logs, job outputs, and experiment artifacts.


This guide shows how to use an NFS server to mount a volume to collect artifacts and artifacts of your jobs and experiments.

This guide uses the click-to-deploy single-node file server on Google Cloud Platform to create a ZFS file server running on a single Google Compute Engine instance, but the same principle applies to an NFS server running on any platform.

Create a Single Node Filer

Using click-to-deploy single-node file server, you need to create a filer: polyaxon-nfs, and keep the default value data, and check enable NFS sharing. You can set the storage to 50GB for example.

Create a folder for hosting your artifacts

Use ssh to create a folder for your artifacts plx-artifacts under /data:

gcloud --project "polyaxon-test" compute ssh --ssh-flag=-L3000:localhost:3000 --zone=us-central1-b polyaxon-nfs-vm
cd /data
mkdir -m 777 plx-artifacts

Get the ip address of the filer

gcloud --project "polyaxon-test" compute instances describe polyaxon-nfs-vm --zone=us-central1-b --format='value(networkInterfaces[0].networkIP)'

You might need to use the correct project name and zone.

Create a PVC with the correct ip addresses

Create artifacts-pvc.yaml containing the following PVS definition:

apiVersion: v1
kind: PersistentVolume
  name: polyaxon-pv-artifacts
    storage: 45Gi
    - ReadWriteMany
    server:  # Use the right IP
    path: "/data/plx-artifacts"
    namespace: polyaxon
    name: polyaxon-pvc-artifacts
kind: PersistentVolumeClaim
apiVersion: v1
  name: polyaxon-pvc-artifacts
    - ReadWriteMany
      storage: 45Gi

Use kubectl to create the PVC based on the nfs server

Under the same namespace where you are deploying Polyaxon, e.g. polyaxon, create the PVC using kubectl

kubectl create -f artifacts-pvc.yaml -n polyaxon

Now you can use this PVC to mount the artifacts volume to your experiments and jobs in Polyaxon

In order to use the PVC with Polyaxon, you can follow the artifacts on Persistent Volume Claim.
